Flat Drop Cable Angled Notch Stripability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat drop cables are robust but difficult to strip due to their strong construction, which hinders efficient installation and maintenance in fiber optic networks.
Innovation Solution
Incorporating angled notches within the jacket of the flat drop cable, offset from the minor axis, to facilitate easier stripping by creating a tear path that intersects the optical fiber, thereby enhancing stripability without compromising the cable's mechanical reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the cable is made robust with strong construction, then mechanical reinforcement and protection are improved, but stripability deteriorates
Solution Approach 1:
The cable structure is segmented by introducing notches that divide the jacket into separable sections. These notches create predetermined weak points that allow the jacket to be stripped away in segments without compromising the overall mechanical reinforcement of the cable during installation and use.
Solution Approach 2:
The notches are positioned at specific locations (offset from the minor axis) to create local areas of reduced strength only where needed for stripping. The rest of the cable maintains its full mechanical reinforcement, achieving localized ease of operation without sacrificing global structural integrity.
2Shape
If notches are positioned on the minor axis, then symmetry is maintained, but stripability is reduced due to interference with the core
Solution Approach 1:
The notches are deliberately positioned asymmetrically relative to the minor axis, offset toward the major axis. This asymmetric positioning allows the notches to fall outside the core region while still providing effective stripability, breaking the symmetry only where necessary to resolve the technical contradiction.
3Ease of operation
If notches are made deep to enhance stripability, then jacket removal is easier, but mechanical integrity may be compromised
Solution Approach 1:
The notches are pre-formed during cable manufacturing to create predetermined stripping zones. These notches concentrate the stress required for stripping at specific locations, allowing easy jacket removal without requiring deep notches that would compromise the mechanical integrity of the remaining cable structure.

AI summary
A flat drop cable has notches or other structures for enhancing the stripability of the jacket from the a core of the flat drop cable. The notches can have an angled configuration with surfaces that converge as the notch extends into the jacket. Inner edges of the notches can be positioned along a tear path that intersects the core of the flat drop cable. For example, the notches can be offset from a minor axis of the flat drop cable a sufficient distance such that the notches are positioned outside a central boundary region that extends tangent to sides of the core and parallel to the minor axis of the flat drop cable.
